winners Ii-nominees 'Ap'piieetlon filed. Il'oveni'oer To all whom it may concern:

Be it known that I, Antonio Bonn Cine a citizen of the United States, and resident of Toledo, in the county of Lucas and. State of Ohio, have invented new and useful 11nprovernents in Window Regulators, of which the following is a descriptioinreferenee heing had to the accompanying drawings, which are a part of this specification.

This invention reietes to window regulators of the quickecting type, particularly dwigned for use in automobile doors where the necessity for directional signaling bys the drivers extended arm makes speedy action in opening and closing the window of great importance.

An object; of the invention is to provide a window reguiator which will. accomplish the full opening movement of the window by a relatively short stroke of the o eretin lever and which will securely hold t e win ow in any position in which it is pieced.

Another object of the invention is to produce such a window regulator that may he operated-with ease and that Wiii he illEXQBD save to manufacture though strong durable.

Another object of the invention. is to pro vide a braking mechenism for Window regulators of this type which wiii he sure in its action and will zilford a. plurality of independent frictional engaging surfaces urged by coiled springs. 1 I

With the above and other ohjects in view the invention consists in the window regw later as herein claimed and all equivaients.

Referring to the accompanying iirawings in which like characters of reierenee'indicute the some galts in clifi'eren'l; views,

Fig. 1 is a iront view of a Window regulator constructed in accordance with this in vention;

Fig. 2 a rear view thereof;

Fig. 3 is a central sectional verticei view thereof;

F i g. 4 is a horizontal sectional view;

Fig. 5 is a view showing the brake menu hers in their relation to the stationary cu or housing;

Fig. 6 is a perspective view of separated. poi'ts in the order of their assembly, and

Fig: 7 is a perspective View of one of the brake disk segments.

In these drawings, indicates a base plate adapted to he secured in place in the member 7, race. semi he; meson automobile door or him like and forming a support for e window-iifting arm 11 of usual construction and an operating lever or handle .12, the handle and arm being connested; together through instrumenielities cooperating to provide free communication of force applied to the handle or lever for swinging the arm to raise or lower the window but to efi'ect', a brake to resist move ments oi the parts from iforce ep lieu to the 3.1111 as by the-weight ofthe win 'ow" The arm llis fixed-on a pivot member 13 and the iatrer is pivotaily mounted in an opening of the base plate, as seen in Fig. 3, a flange M- 'of the pivot member bearing against the Toe cl: of the base plate. The arm has a wrench-hold engagement with the pan zillel shoulders 15 of the pivot member and-is riveted thereto by turning over the feathered edge 16 thereageinst. The outer end'of the arm ll supgiorfs the window in the usual manner and the weight or the winciow is coun'berhaianced by a heiicai spring 1'1 wounrlehout and engaged with. the slotted boss 18 on the rear end oi the pivoh memher with its .aoobshaped outer endengageci with a, flange l9 bent up from the base plate. One or more openings 20 me he provided in the flange 19 to eiiord ed itionei jnoints of engogement, for the hooked end of the spring whereby an adjustment may be made to very the action of the sprin so as to properly counterbalance the win ow The handle 12' is fixed on haniiie shaft 21, which is journuleci in a cup-shaped hearing member lined in place by being riveted to the base plate 10. A flange 23 on. the

handle shaft bears against the 1111182 well of the stationary cup or casing 22 and the handle member may he keyed on the shaft by fitting on the parallel wrench shoulders A, where it is held by the head of e screw 2-5, as shown.

. Inside the oupshaped bearing member 22 the handle shaft 21 has rigidly secured to it a driving yoke or earn 26 with a. pair of parallel yoke fingers 27. As shown, the driving member consists of a disk I'iitin on parniiel wrench shoulders 28 on the on of; thehendie shaft 21 and riveted in niece by leaving feathered edgesiii) on the end of the shaft bent over thereageinsisj Contained within the cup-shaped hearing and ir-ictionelly engaging the cylindrical wells thereof are a number of expending sectional disks 30 forming brake members and constituting the driving coir neotion between the handle 12 and arm. 11 by having notches 31 in their outer edges receiving the parallel lingers 27 of the driver 26 and by having rectangular central open huge 32 receiving a square cam projection 33 on the end of the pivot member 13. Coiled springs 34- are contained in' re istering notches at the inner edges of the cisk sections tending to expand the disks into trio tionul engagement with the cylindrical walls of the cup-shaped bearing member and the disk sections are held in place by being confined between the flange 1% of the pivot 1116111- ber and an embossed ring 8:) formed on the driver 26, as seen in Figs. 3 and 4.

From the foregoing it will be obvious that the effect of the coiled springs ill-is to expand the brake disks 3O into'frictional engagement with the cylindrical. wall of the cup-shaped bearing member 22 to hold all parts against turning. The weight of the window supported by the arrn- 11 tends to turn the pivot member 13 but the wedging action of the square projection thereof between the disk sections tends to push them apart with greater force and into a tighter fitting relation with the walls of the cupehapecl nieniber to increase the resistance to turning movement. ,lressure applied to the handle member 12 in either direction will, however, release the engagement of the friction disks by the turning movementof the fingers 27 tending to press the disk sections together against'the action of springs 34:. By releasing the frictional engagement of the disks the parts turn free- 1y, motion being communicated from the handle member to the window-supporting arm through the'driving connection formed by the disks between the fingers of the driver 26 and the square projection on the pivot member of the arm. This freedom of action is the same whether the handle is turned for raising or lowering the window and the direct connection between the handle and the arm enables the full openingor closing movement of the window L0 be accomplished by the some are of movement of the handle that is given to tho window-supporting arm, which, in practice, is approximately Thus, because of the effective brake for rigidly holding the window in any position, the-handle may be directly connected with the window arm and the full movements of the window may be produced by means-oi short stroke of the handlc'to accomplish the quick opening and closing; of the window for hand signaling purposes.

While the expanding friction member is preferably in the form of a number of segmental friction disks, in order to obtain increased frictional beurin surface, it may consist of a single expanding disk member connection with the disk sections,

and the cam 33 may have any form that will cause it to wedge the disk sections apart when turned.

What I claim as new and desire to by Letters Patent is:

1. A brake comprising a bearing member hovinga cylindrical wall, a sectional disk normally bearing against said wall, a drivin member having engagement witl1.the disk sections near their peripheries, and a driven. member having a cam fitting between the disk sect-ions.
